Answer:
m = 10 , n = 5
Step-by-step explanation:
using the cosine and tangent ratio in the right triangle and the exact values
cos45° = 
and tan45° = 1 , then
cos45° = 
= 
= ( cross- multiply )
m = 5 × = 5 × 2 = 10
-----------------------------------------
tan45° = 
= 
= 1 , then
n = 5
Answer:
9
Step-by-step explanation:
The average is just another word for mean. You get the mean by adding all the numbers in a data set and then dividing by the number you added.
First find the slope of the line:-
= (0- - 9) / (3 - 0) = 9/3 = 3
Now use the point slope form of the equation to plug in the point (3,0):-
y - y1 = 3(x - x1)
y1 = 0 and x1 = 3:-
y - 0 = 3(x - 3)
y = 3x - 9 is the answer Its D.
